Scientists have created a coronavirus killer lamp

American scientists have found that a wave of blue light of a certain length kills COVID-19. This discovery will allow continuous disinfection of the premises, objects, and even the mucous membranes of a person

Ultraviolet disinfectant with side effects Researchers at several US institutions and EmitBio medical engineers have tried to find wavelengths of ultraviolet light that will disinfect surfaces without harming humans. UV rays kill most bacteria, viruses and fungi, but their use is limited: in high doses, they cause burns to the skin and destruction of the cornea of the human eye. UV light can also damage the genome. Scientists have decided to find out what effect blue light will have with wavelengths close to the ultraviolet boundary. To do this, they conducted a two-stage experiment with LED luminaires with wavelengths of 385, 405 and 425 nanometers. The results of the researchers were published in the journal Nature in the fall of 2021. Blue light does not harm a person At the first stage, scientists checked whether radiation with three wavelengths can be harmful to a person. To do this, they took the donor tissues of the bronchi and the trachea and created...
